No one wants to answer him :( ? I'll give my take on it then!
I think Jamitov was just courting Axis to distract them. Better to have more friends, that way you'll have less enemies. He planned on building up more military power, like that colony laser. With the help of Axis he doesn't have to spend his full power dealing with the AEUG, this means he can spend his resources strengthening the Titans until they have enough power to wipe out Axis and take over the solar system.
